, KEY-RING.

To all whom it may concern:

Be it known that I, CHARLES SOHUMAOHER, a citizen of the United States,and a resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented a new and Improved Key-Ring, of which thefollowing is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide a ring of the character mentioned, having arms frictionallyheld to form a rin to provide a pivot eyelet for attachment to a chain;and to provide a device of the construction set forth with a pluralityof operating handle members arranged to afford a plurality ofadvertising plates, two of which are covered during the major portion ofthe time.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in whichFigure 1 is a side view of a key ring constructed and arranged inaccordance with the present invention; Fig. 2 is a longitudinal sectiontaken on the line 22 in Fig. 1; Fig. 3 is a side view of a ringconstructed and arranged in accordance with the present invention, thesame being shown in its open position; and Fig. 4 is a perspective viewof one of the duplicate parts from which the ring is constructed.

As seen in the drawings the rings are constructed from duplicate parts.Each of the parts is provided with a hook 9 and a folding plate 10.Intermediate the plate and hook is a hinge portion 11. The portion 11 isprovided with a perforation 12. Both faces of the plate 10 may beutilized for advertising for amusement purposes. One of the said faces,it will be noted by referring to Fig. 1 of the drawings, is coveredunder normal conditions of use of the ring constructed in accordancewith the present invention. The ring, as shown in Fig. 1 of thedrawings, is formed by the hook 9 of the duplicate parts when the sameare overlaid and pivotally connected by means of an eyelet 13. Theeyelet 13, as in similar constructions, is provided with flanges 14:,1A. The opening in the eyelet is of suflicient size to receive a snaphook or other suitable fastening device provided at the end of aretaining chain. It is to hold the hooks 9 in Specification of LettersPatent.

position to form the ring, as seen in Fig. 1 of the drawings, that Ihave provided the serrated friction surfaces 15.

The operation of a key ring when constructed and arranged in accordancewith the present invention is as follows :When the ring is in positionas shown in Fig. 1, the hooks 9, 9 are overlaid that their surfaces 15,15 bear against the side of the opposite hook. The hooks are slightlysprung to accommodate this action, as shown in Fig. 4: of the drawings.The spring of the hooks 9, 9 is compensated by the arrangement of theplates 10, 10 which overlie each other and resist the spreading actionof the hooks when depressed. Then it is desired to remove a key from thering thus formed, the plates 10, 10 are grasped between the thumb andfinger of the operator, when by forcing one past the other the hooks arespread as shown in Fig. 3 of the drawings. By reversing the operation,the hooks are closed to form the ring as shown in Fig. 1 of thedrawings.

As indicated, the plates 10, 10 are employed by me as means foradvertising certain articles and for imprinting thereon the name andaddress, or other information relative to the owner whereby, if desired,the ring may serve as a partial identifying article. The plates 10, 1Ofolding, as seen, one upon the other, the adjacent surfaces may beprovided with a pictorial or other representation which is preservedfrom wear and exposure when the ring is folded to the operating positionshown in Fig. 1 of the drawings.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. As an article of manufacture, a key ringhaving a plurality of duplicate members each having a median perforateddisklike hinge section, each of said members having extended from oneside of said hinge section a hook and at the other side of said.

hinge section a disk-like extension adapted to form an operating handlefor said hooks, and an eyelet pivot operatively connecting saidduplicate members.

2. As an article of manufacture, a key ring having a plurality ofduplicate members, each member having a median perforated disk-likehinge section and each member having extended from one side of saidhinge section a hook the side whereof is provided with a frictionbearing surface, said members being further provided at the op- Intestimony whereof I have signed my posite side of said hinge sectionwith a disk name to this specification in the presence of section, saidduplicate members being so two subscribing Witnesses.
